Russian wheat export prices registered a fourth consecutive weekly decline last week, dragged down by competition with other major exporters, but the pace of the fall has slowed, SovEcon agriculture consultancy said on Monday.

Global commodities markets are under pressure from risks related to the coronavirus outbreak. But the prospects for the 2020 Black Sea crop look good so far with 83-87 million tonnes of wheat expected in Russia, higher than for 2019, and 26-28 million tonnes expected in Ukraine, roughly flat year-on-year, SovEcon added.

Russian wheat with a 12.5% protein content, loaded from Black Sea ports, fell by $2 to $218 a tonne free on board (FOB) at the end of last week, SovEcon said. Barley was down by $2 to $190 a tonne. "The decline in the market has slowed down as Russian wheat regains its competitive edge," SovEcon said in a note. A week earlier it registered a $6 fall.

Global benchmark Chicago wheat futures slid for a fourth consecutive session on Monday as fears over the rapid spread of the coronavirus outbreak beyond China depressed commodities and shares. Russia, the world's largest wheat exporter, and Ukraine along with neighbours such as Romania compete for supplies of their wheat to Africa, the Middle East and Asia via the Black Sea.
